Nice.  It's too bad Firestarter doesn't permit comments in that file, or
I would just paste that in.  (Changing the script to do that would be
trivial but I would lose it in the next upgrade).

The non-routables file had 42 lines of /8's and a few of the ones above.
 I cleared them all out.

Thanks!

While I'm on this winning streak, let me ask one question I've never
been able to get an answer on: I *HATE* the fact that all these iptables
log messages take over /var/log/messages.  I've seen ways of writing
them elsewhere in addition to /var/log/messages, and I've seen ways of
writing all kernel warnings to another file, but never a way of writing
just iptables output (and all of iptables output) to just
/var/log/iptables.log (or whatever).   Is there a way?
